Description

柯萨奇病毒A组6型(CVA6)的小鼠强毒力攻毒株及其应用
技术领域
本发明属于医药生物技术领域,具体而言,涉及一种柯萨奇病毒A组6型(CVA6)的小鼠强毒力攻毒株及其应用。
背景技术
2012年以前在中国大陆大多数地区引起手足口病的主要的肠道病毒血清型为EV71和CVA16,且重症病例和死亡病例以EV71感染为主。而近年的流行病学调查结果显示,CVA6已经成为引起手足口病的主要肠道病毒血清型,在一些地区其比例甚至已经超过50%。例如2013年吉林省长春市发生手足口病疫情,CVA6在病原谱中占比66.9%[1]。因CVA6感染而引起的重症病例也呈明显上升趋势[2]。除此之外,CVA6感染病例还具有其他重要特征,如导致成人感染患病[3]。患者临床症状往往并非典型的手足口病,而是头皮、耳朵、脸颊等全身多部位的丘疹、紫癜和疼痛性水泡疹,并伴有发热、神经系统症状和关节炎[4]。所以为了更全面的预防手足口病,需要研发包含多种肠道病毒抗原的多价手足口病疫苗,而CVA6为多价手足口病疫苗的重要抗原成分。
在疫苗的研发过程中,需要建立合适的感染模型对候选疫苗的效力进行评价,最常用的感染模型仍然是小鼠模型。国际学术期刊已发表的文章更多采用的是小日龄乳鼠的被动免疫保护模型,包括使用抗血清的预防性和治疗性被动保护模型和母传抗体被动免疫保护模型。被动免疫保护模型虽证实了中和抗体的保护作用,但不能模拟自然状态下疫苗免疫和病毒感染的过程,不能反映动物接种疫苗后的体液和细胞免疫应答及攻毒后的保护效力。所以更好的用于评价疫苗效力的动物模型是主动免疫保护模型,即使用候选疫苗直接对小鼠进行免疫并对小鼠进行攻毒。而大日龄小鼠对包括CVA6在内的柯萨奇A组病毒不敏感,使攻毒前没有初次免疫和加强免疫的窗口期,是主动免疫保护模型建立的技术障碍。因此,主动免疫保护模型建立的核心技术是获得能感染14日龄小鼠的攻毒株,使得新生乳鼠获得间隔一周的2次免疫,加强免疫后第5日中和抗体出现后进行攻毒,观察攻毒后14日龄小鼠的发病及致死率,与未免疫攻毒的对照组比较,以免疫攻毒组的小鼠存活率或发病保护率,计算候选疫苗保护效力。

本发明的有益效果是:本研究使用基因组已测序、遗传背景清晰一致、可在RD细胞传代的克隆纯化株CVA6-P8-(13-5)作为出发毒株,采用颅内注射途径,感染日龄逐代增大的ICR小鼠。每代小鼠发病濒临死亡前,取其脑组织制备匀浆液,在RD细胞传代1次,获得高滴度毒株库,再次鼠脑传代。依次在1日龄、5日龄、7日龄、10日龄、12日龄小鼠中传代,获得可使12日龄小鼠致病、致死的强毒力小鼠适应毒种库CVA6-P8-(13-5)-P6+R8。对其进行克隆纯化,获得可使12日龄小鼠致病、致死的强毒株CVA6-S4。对其进行全基因组序列测定,与小鼠适应前的弱毒力CVA6-P8-(13-5)株进行比较,确定与小鼠体内毒力相关的核苷酸、氨基酸突变位点。
将CVA6-S4病毒在RD细胞传代扩增,对病毒收获液进行浓缩制备病毒浓缩液,并以高感染剂量(9.48x106CCID50/剂/只)感染14日龄小鼠,使得2周内100%小鼠致病、83.3%小鼠致死。使用全病毒灭活实心颗粒FP作为实验用疫苗,间隔6日免疫新生乳鼠两次后,以6-12个半数致死剂量(LD50)CVA6-S4攻毒,可以保护100%的14日龄小鼠抵抗CVA6-S4的致死性攻击,而未免疫攻毒组100%小鼠死亡。因此,成功建立了可用于候选疫苗效力评价的主动免疫保护模型。

病毒的培养
待T型瓶中RD细胞汇合度达到或接近100%时,于生物安全柜中先用适量无菌的0.01M的PBS溶液润洗细胞2次。然后加入适量的细胞维持液,按照一定的感染复数MOI加入已知滴度的病毒液。并置于37℃的CO2培养箱中静置培养。
病毒的收获及保存
倒置显微镜下观察接种病毒后的细胞状态,待细胞病变达到80%~90%后,转移培养瓶至-20℃冰箱中,然后反复冻融3次后转移至无菌离心管中,7,000g,离心10min使病毒液与细胞碎片分离,将病毒液分装至无菌离心管中,-80℃保存。
病毒的滴定
(1)倒置显微镜下观察T瓶中的RD细胞,当细胞汇合度达到或接近100%时,于超净台中先弃去旧的细胞培养基,然后用适量无菌的0.01M的PBS溶液润洗细胞2次。再加入适量的或TrypLE Select(RD细胞),于室温的CO2培养箱消化,至细胞完全脱落。加入适当细胞培养基将细胞密度调整至1×105~1.5×105个/mL,将细胞悬液加入到96孔板中,100μL/孔,37℃,5%CO2培养箱中静置培养。
(2)取24孔板,每孔中先加入1350μL的病毒稀释液。取150μL的病毒原液加入到第1孔中,随后依次进行10倍的梯度稀释。
(3)将各个稀释梯度的病毒稀释液悬空滴加到步骤(1)中的96孔细胞培养板中,每一个稀释度加入纵向的8个孔,每孔100μL,置于37℃,5%的CO2培养箱中培养。
(4)7天后于倒置显微镜下观察细胞病变情况,统计每个稀释度出现CPE的孔数;按Reed-Muench法计算公式计算病毒的滴度。LogCCID50/mL=d×(高于50%的病变率-50%)/(高于50%病变率-小于50%病变率)+XN,公式中:d=稀释度系数的对数(10倍稀释为1),距离比例=(高于50%的病变率-50%)/(高于50%病变率-小于50%病变率),XN=高于50%的病变率的病毒稀释度负对数。
病毒的鼠脑及细胞交替传代
(1)1mL注射器使用前进行干烤灭菌。乳鼠脑内接种时用左手大拇指与食指固定鼠头,用70%的酒精棉对头颅部位进行擦拭消毒,然后于颅脑处进行注射,进针2-3mm,注射量依据乳鼠的日龄数,即1日龄注射10μL,5日龄和7日龄注射20μL,更大日龄则注射30μL。观察期两周。两周内若出现濒死时则回收乳鼠鼠脑和各个组织器官,包括心、肝、脾、肺、肾和后腿(按需所取)。
(2)在生物安全柜中对濒死的乳鼠进行解剖并取出鼠脑和其他组织器官称重,按质量体积比10%(g:10ml)加入无血清的MEM培养基,使用玻璃匀浆器匀浆,制备组织匀浆。4℃,12,000g离心10min,取上清保存。
(3)将鼠脑匀浆液100μL接种到RD细胞汇合度100%的T25细胞培养瓶中,37℃,5%CO2培养箱孵育,每日观察细胞病变情况。待病变程度达到80%时,进行3次反复冻融。4℃,6,000g离心10min除去细胞碎片,吸取上清病毒液,并对上清病毒液和鼠脑匀浆液进行滴定。于-80℃保存,待下次鼠脑传代使用。
病毒的空斑纯化
(1)细胞的6孔板培养:倒置显微镜下观察T瓶中的RD细胞,当细胞汇合度达到或接近100%时,于室温消化,使细胞完全脱落。加入细胞培养基并调整细胞密度至1×105~1.5×105个/mL,往6孔板的每个孔内加入3mL的细胞悬液,37℃的CO2培养箱中培养。
(2)病毒的稀释:将待空斑纯化的病毒原液进行10倍梯度稀释,稀释范围为10-1~10-6
(3)病毒的吸附:待6孔板中的RD细胞长成致密单层后,于生物安全柜中吸弃旧的细胞培养基,无菌的0.01M的PBS溶液润洗细胞2次。将200μL的稀释范围为10-1~10-6病毒稀释液分别接种到每个孔内,轻轻晃动6孔板使病毒稀释液均匀覆盖到细胞表面,37℃的CO2培养箱孵育1h,孵育过程中每隔10min晃动一次6孔板。
(4)覆盖:将2×MEM培养基与融化好的3%的低熔点琼脂糖胶液等体积混合制成覆盖液,放于65℃恒温加热器中保温备用。待病毒稀释液吸附1h后将其吸弃,无菌的0.01M的PBS溶液润洗细胞2次。待覆盖液略微冷却后,向每孔中加入3mL的覆盖液。室温冷却凝固后放入37℃的CO2培养箱培养。
(5)染色:当肉眼可见6孔板中有空斑形成,且镜检确定为细胞病变时,加入含0.01%中性红染色液的1%琼脂糖胶液,每孔加入1.5mL,放入37℃的CO2培养箱培养。
(6)挑斑:使用200μL的移液枪搭配带滤芯的枪头,对准、插入并吸取要挑取的空斑,加入到200μL的病毒维持液中,以备连续的空斑纯化或扩大培养。
(7)连续空斑纯化:将步骤(6)获得的空斑稀释液进行10倍的梯度稀释后,重复步骤(1)到步骤(5)。
实施例1、小鼠强毒株CVA6-S4的选育及体内毒力比较
以实验室肠道病毒库的一株从RD细胞分离、培养8代,并通过末端稀释法获得的,已完成全基因组测序、遗传背景清晰一致的单克隆株CVA6-P8-(13-5)作为出发母毒株,在ICR小鼠颅内和RD细胞之间交替传代6次后,获得能够稳定致死12日龄ICR小鼠的毒种库CVA6-P8-(13-5)-P6+R8(图1)。
由于CVA6-P8-(13-5)-P6+R8的原倍病毒液浓缩120倍后可以致使14日龄ICR小鼠后肢麻痹瘫痪,所以对其进行三次连续的空斑纯化,挑选高致病率的克隆株。在第一次空斑纯化时挑取8个空斑分别标记为CVA6-S1、CVA6-S2、CVA6-S3、CVA6-S4、CVA6-S5、CVA6-S6、CVA6-S7和CVA6-S8,并进行空斑到空斑的连续三次纯化,获得6个可稳定克隆传代的毒株。
将三次连续空斑纯化后获得的CVA6-S1、CVA6-S3、CVA6-S4、CVA6-S6、CVA6-S7和CVA6-S8克隆株分别在T25培养瓶中扩增一代后,分别再次感染12日龄ICR小鼠,结果显示。CVA6-S3和CVA6-S7对12日龄ICR小鼠的致死率为100%,但发病日程较长,均为第7天才开始出现致死。强毒株CVA6-S4对12日龄ICR小鼠的致死率虽只有约60%,但发病最快,第3天时9只ICR小鼠全部表现为后肢麻痹瘫痪,第4天开始出现致死(如图3所示)。于此相比的,CVA6-S6对12日龄ICR小鼠的致死率为80%,且发病日程也较长,不适合作为攻击毒株。CVA6-S1和CVA6-S8对12日龄ICR小鼠完全无致死性,属于弱毒株。上述结果表明,毒种在小鼠体内和RD细胞中传代过程中,毒株发生适应性突变,各克隆株的毒力有显著差别。
取强毒株CVA6-S4,测定克隆株毒力。并对母株和适应毒株毒力进行比较(表1)。当感染剂量为4.74x105CCID50时,强毒株CVA6-S4对12日龄ICR小鼠的致死率为55.5%(5/9),对14日龄ICR小鼠的致死率为0(0/9)。而当感染剂量为3.80x 106CCID50时,出发母毒株CVA6-P8-(13-5)对12日龄ICR小鼠的致死率为20%(2/10),对14日龄ICR小鼠的致死率为0(0/9)。当采用高剂量的CVA6-S4,即9.48x 106CCID50时,其对14日龄ICR小鼠的致死率为83.3%(5/6)。通过不同剂量感染试验计算获得CVA6-S4对14日龄ICR小鼠的半数致死剂量LD50为4.1х106CCID50/mouse。出发母毒株CVA6-P8-(13-5)与强毒株CVA6-S4在大日龄小鼠上的毒力差别显著。

实施例2、候选疫苗的免疫及效力测定
取2窝3日龄的ICR乳鼠,每窝1只母鼠带领6只乳鼠。一窝为实验组,免疫Al(OH)3佐剂吸附的1μg的全病毒灭活实心颗粒(FP),另一窝为对照组,免疫与实验组相同剂量的Al(OH)3佐剂。待9日龄时各自加强免疫一剂。乳鼠14日龄时,采用6个LD50的CVA6-S4对两组乳鼠进行攻毒(图1)。结果显示,对照组乳鼠全部患病致死,而1.0μg的FP组无明显发病,存活率为100%(图2)。
实施例3、攻毒株CVA6-S4毒力位点分析
出发母毒株CVA6-P8-(13-5)和强毒克隆株CVA6-S4全序列进行测定并分析比对核苷酸、氨基酸的变异(表2),CVA6-P8-(13-5)与CVA6-S4相比,基因组共5个核苷酸位点突变,分别位于第1371,2261,3245,5288和6926位碱基(表3和表4)。且均引起氨基酸突变,位于5个病毒蛋白,分别为VP2-T139M、VP3-I180V、VP1-V268L、3A-A66T、3D-E321Q突变。因此,二者核苷酸和氨基酸位点的在传代过程中的突变,与毒力密切相关。
